Fear River — R.H. Johnson

Mayhem and murder roil the usually calm waters of the St. Lawrence River. The story is set in the bucolic Thousand Islands region of New York State, where the wealthy enjoy the good life amid the splendor of their cozy private islands. But nothing is as it seems in the tiny riverfront town of Rampart, and even the local police chief seems indifferent to a recent crime spree. It's up to a pair of NYPD homicide detectives to solve a homegrown mystery that has turned the sleepy community upside down.
